4-2 Testing the Balance
The amount of offset with respect to the reference weight can be checked. This is called “span
test.”
Performing a span test will not calibrate the balance.
参 考
Use a weight for calibration that weighs 50% of the weighing capacity or heavier. To calibrate
more accurately, use a weight that is equivalent to the weighing capacity.
Please contact us if you wish inquire about or place an order for calibration weights.
